If your child is a chronic liar, all you have to do is get them on the Jimmy Kimmel show and the truth will start flowing.

Jimmy Kimmel has a segment called "Lie Detective" where he gives an innocent child a fake polygraph test. Only the kids don't know it's fake (despite the obviously unofficial colander worn as a hat).

At Jimmy's discretion, an alarm sounds when he thinks the child may be lying. In some of the videos, the child denies it, probably because he or she isn't actually lying.

However, the little boy in this video is all-to-eager to give himself up when he lies.
